The military and intelligence communities face a difficult challenge - the need to monitor communications over a very wide frequency range without being detected. Present electronic surveillance systems employ multiple antennas that are either large or noisy. ANTENNA EXPERTS antenna systems provides passive antennas in compact, versatile form factors that provide extreme wideband performance for surveillance application, signal intelligence SIGINT application and electronic warfare EW applications.
The LP series ranges of log periodic dipole array are high gain array that provides strong performance over the operating frequency range of 10 MHz to 6000 MHz. as the log periodic dipole array does not use loading technique to reduce the overall size of array. These log periodic dipole antennas uses 6063T6 ultra corrosion resistant architectural aluminum alloy and designed to provide wideband directional transmission/reception of radio signals from 10-6000 MHz bands. The log periodic antennas are suitable for receiving, transmitting, scanning, monitoring and jamming applications due to its broadband design feature. The LP series LPDA features high power handing capabilities, high efficiency, low VSWR, low loss and robust mechanical design to accommodate the most extreme environments condition. The complete antenna is supplied with powder coating finish to protect it further for severe weather.
The LP-20-3000L tactical log periodic dipole antenna is small size log periodic antenna and designed to provide wideband directional transmission/reception of radio signals from 20-3000 MHz bands. The compact size of tactical log periodic antenna is supplied with powder coating to protect it further from severe environmental conditions. The specially designed mounting arrangement results in fast installation. The compact size tactical LP antenna can be assembled in less than 10 minutes. This compact size tactical log periodic dipole antenna system is particular suitable for transmission, reception, monitoring application, surveillance application, signal intelligence application, electronic warfare application scanning application and jamming application due to its broad band design feature, small size and high power handling capacity. This compact size tactical log periodic antenna uses loading technique to reduce the overall size of array. The shipping length of antenna is 6 feet making it highly suitable for mobile and tactical applications.
The LP-20-3000L assembled compact size tactical log periodic antennas outer-most dimensions are 3 meters (10 feet) long and 3 meters (10 feet) wide. The small size tactical LP antenna has removable elements, the longest of which is 1.5 meters. Similarly the support boom of compact size log periodic antenna is supplied in two sections for easy of shipping/carrying/transportation and handling. All elements of small size LP antennas are supplied in two segments for easy of shipping and handling. The elements are attached via a fast deployment stainless steel studs & nuts system at points along the boom. The small aperture tactical log periodic antenna operates at D.C. ground with low resistance discharge path for protection against lightning and immunity to noise. All the screws, nuts and bolts of low profile tactical log periodic dipole antenna are made of type 316 marine grade stainless steel.
The LP series antenna has removable elements, making these LP antennas highly suitable for easy of shipping/carrying/transportation and handling. All elements are supplied in two segments for easy of shipping and handling. The elements are attached via stainless steel nuts & bolts systems at points along the boom. The powder coating on complete log periodic dipole antennas surfaces ensures complete protection from corrosive gases, ultraviolet radiation, salt spray, acid rain and sand storms in desert environments also provides extra protection against corrosion in saline weather present in coastal areas. The coaxial cable of log periodic dipole antennas sealed inside the support boom to make it weatherproof. The Log Periodic Dipole Array operates at D.C. ground with low resistance discharge path for protection against lightning and for immunity to noise. Log periodic dipole antenna above 300MHz are supplied complete in assembled conditions. Optionally these UHF log periodic antenna can be supplied with radome/housing.
